Pics: Pitra Paksha importance and rules

The shraddha is performed on the specific lunar day during the Pitra Paksha, when the ancestor—usually a parent or paternal grandparent—died. There are exceptions to the lunar day rule; special days are allotted for people who died in a particular manner or had a certain status in life. Chautha Bharani and Bharani Panchami, the fourth and fifth lunar day respectively, are allocated for people deceased in the past year. Avidhava navami ("Unwidowed ninth"), the ninth lunar day, is for married women who died before their husband.
